How this service works
Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.
Output
Returns a JSON object with an 'ok' boolean field indicating whether the credential signing was successful, along with any signed credential or artifact data produced by the service.
Example use cases
Agent workflow credential signing
“I need to sign the credentials for a JSON POST request in my automated agent pipeline — can you use the DDG signing service to authenticate this body payload and give me back the signed artifact?”
Form-data authentication for agent
“Sign this form-data PUT request body using DDG's credential signing endpoint so my agent can submit it with proper authentication.”
Micropayment-gated request signing
“Use the DDG agent-payable signing service to sign a PATCH request with a JSON body — I want a verified signed credential back for this HTTP operation.”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/credentials/sign?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to obtain a cryptographically signed credential or artifact for an HTTP request body within a machine-payable workflow that supports x402 USDC micropayments. Prefer this when you need bounded, signed artifacts rather than raw provider account access, and when your agent runtime supports x402 payment rails.
Side effects

- Unsupported HTTP method (only POST, PUT, PATCH allowed) — returns 422 Unprocessable Entity
- Unsupported bodyType (must be json, form-data, or text) — returns validation error
